Summary

All samples were fire assayed with either an ICP-MS finish if it was a soil or sediment sample or an ICP-AES finish, if it was a rock sample; to detect gold, palladium, and platinum. Suspected high-grade samples were analyzed using the same ICP-MS or ICP-AES methods but the instruments were calibrated to higher detection limits. Samples with gold and silver assay results that exceed their respective ICP analysis detection limits, at the discretion of the lab, were reanalyzed by fire assay with either a gravimetric finish, or by Atomic Absorption Spectroscopy (AAS). After the fire assay, a split of the sample pulp was partially dissolved in aqua-regia. The resulting solution was analyzed using a combination of ICP-MS and ICP-AES. AAS [...]
